AUDI TT 1.8T 20v A3 -A4 - TT - S3

SUPERTECH forged piston set for  AUDI A3, A4, TT, S3 engine 1.8T 20v all models. 

SUPERTECH, has extensive experience of more than 40 years in the manufacture of high performance forged pistons.
Supertech pistons are manufactured using technology transferred from European manufacturers. SUPERTECH pistons are designed and manufactured to guarantee maximum durability and at the same time offer the highest performance features.
Our pistons are manufactured from 4032 enhanced high silicon alloy (with additional Cu, Ni and Mg) which has low thermal expansion and exhibits excellent wear resistance. Additionally, the inclusion of the improved 4032 alloy offers much higher thermal conductivity.
With this alloy, the Supertech pistons have withstood up to 42 Psi (2.89 bar) turbo pressure with alcohol, without a problem.
Depending on the type of piston, we have a 2 or 3-step forging process that produces a fine structural grain that orients the fibers in the same direction of stress, all combined with various heat treatments and thus have a uniformly distributed hardness. and extremely high tensile strength.
From there, each Supertech piston goes through several machining steps specifically designed to ensure dimensional accuracy, perpendicularity, and ring groove revision.
The characteristic color of SUPERTECH pistons is due to a dry phosphate coating.
The piston pins are made of chrome moly steel, cold drawn for greater resistance.
Segments are manufactured in Japan with the latest technology for high performance applications.
Quality control in all products.

The indicated price includes the complete set of all pistons, rings and pins.
